NP (RIT, RT) | Cylindrical Bearings

Cylindrical bearing type NP has a double-ribbed inner ring and a single-ribbed outer ring with an abutting loose rib, which allows the bearing to provide axial location and to carry light thrust loads in both directions. Factors governing radial and thrust load capacities are the same for Types NJ.

Size range: 80 mm to 2000 mm OD

Design Attributes

Design features an inner ring with two integral ribs and an outer ring with a single rib.

Features an abutting loose rib.

Carries light thrust loads in both directions.

Provides axial location.

May be used with RN or RU bearing to accommodate axial expansion/contraction.

A type NP bearing may be used in conjunction with a type RN or RU bearing for applications where axial shaft expansion is anticipated. In these cases, the fixed bearing is usually placed nearest the drive of the end shaft to minimize alignment variations in the drive. Shaft endplay (or float) is determined by the axial clearance in the bearing.

Engineered SurfacesEngineered surfaces help protect bearing components by minimizing skidding and sliding damage while withstanding small-particle contamination. In some cases, engineered solutions extend bearing life by up to five times that of standard designs, especially in demanding applications.

LubricationProper lubrication is an important component of maximizing bearing life and reducing downtime. Timken offers a full line of greases that are compatible with bearings used in a variety of applications.
